Definitions

  • the present disclosure relates to an injector for intravenous and intra-arterial application of parenteral solutions from containers that contain a multiplicity of individual doses of the parenteral solution.
  • Cartridge injectors are known, which apply individual doses from cartridges and these cartridges are either empty and are to be filled by the user from single or multi-dose containers with the parenteral solution (WO2004/091688A2), or the cartridges are already pre-filled with the parenteral solution (U.S. Pat. No. 6,673,033 B1).
  • pump injectors are known for removing solutions from containers, which contain a multiplicity of doses of a parenteral solution (multi-use container), and for transferring the removed solution to the patient.
  • these injectors are operated by a peristaltic pump and operate as continuous flow systems.
  • RFID radiofrequency identification
  • the RFID chip has an electronic data storage device and thereby enables reading out information with the aid of a reader.
  • the RFID chip is used to transfer information from the cartridge to an injector. Transferred information includes information such as the product name, amount specifications, batch number, expiry date of the cartridge, and pressure limit during the removal from the cartridge.
  • the problem of known injectors consists of the users running the risk of applying too large of a dose of the solution if a container is used that contains a multiplicity of doses of a parenteral solution, or from large cartridges that contain a plurality of doses, since there is no restriction by the defined maximum filling volume like in the single-dose cartridge. Furthermore, there is the risk of using the container or the large cartridge after the first removal for a longer period of time than can be justified for microbiological reasons because there is still solution in the container or the large cartridge once the maximum justified usage duration, which is also specified by the manufacturer, has passed after opening.
  • the solution of the specified object consists of the injector described below.
  • the injector can be a pump injector or a cartridge injector for large cartridges.
  • multi-dose container comprises all types of containers, bottles or bags.
  • large cartridge denotes a cartridge or large bottle that is emptied by piston pressure and contains a plurality of doses of a liquid to be applied.
  • the injector according to the present disclosure is suitable for being connected to one or more multi-dose containers for fluid transfer.
  • Known connections for liquids e.g. tube connections
  • the output of the cartridge is connected to a patient via known connections for liquids (e.g. tube connections).
  • the connection can for example open into a venous catheter.
  • parenteral solution can be removed from respectively one or more multi-dose containers or large cartridges, and injected individually or, optionally, in parallel.
  • the multi-dose containers or large cartridges contain parenteral solutions that are applied to the patient.
  • Each multi-dose container or large cartridge contains a multiplicity of doses for being applied to a multiplicity of patients.
  • a container data storage device that can be read wirelessly or via a cable connection (READ function) is fixedly connected to each multi-dose container or to each large cartridge.
  • the container data storage device can optionally also be written to in the same manner (WRITE function).
  • the container data storage device may be a radiofrequency identification (RFID) chip.
  • RFID radiofrequency identification
  • Other types of optical and/or electronic data storage devices e.g. one-dimensional codes (bar codes), 2D codes (data matrix) or holographic storage devices, are likewise suitable as a container data storage device.
  • At least specifications relating to the identity of the product situated in the multi-dose container or the large cartridge are stored in the container data storage device. In addition to these specifications in respect of the identity of the product, it is possible to assign product data, or other relevant data stored in other data storage devices, to the multi-dose container or the large cartridge with the corresponding container data storage device.
  • further information can also be stored in the container data storage device, for example product specific information such as batch number, maximum individual dose and maximum usage period after opening the container, expiry date or filling volume.
  • the multi-dose containers or large cartridges contain parenteral solutions that are suitable for the examination, preferably a salt solution or a contrast agent.
  • the pump injector has at least one processor, one pump, one injector data storage device and one device for data transfer.
  • the processor is electronically connected to the injector data storage device, to a control unit for the pump and to the device for data transfer.
  • the device for data transfer is suitable for reading out the data from the container data storage devices.
  • the cartridge injector has at least one processor, one motor with advance for the piston, which drives the liquid out of the cartridge, one injector data storage device and a device for data transfer.
  • the processor is electronically connected to the injector data storage device, to a control unit for the motor and to the device for data transfer.
  • the device for data transfer is suitable for reading out the data from the container data storage devices.
  • Information in respect of different products and/or batch numbers can be stored in the injector data storage device.
  • This information includes at least the maximum individual dose and the maximum usage duration after opening the container. Further information available in the injector data storage device can be the batch number, maximum individual dose and maximum usage period after opening the container, expiry date or filling volume.
  • the device for data transfer of the injector is suitable for reading data from the container data storage device wirelessly or via a cable connection and, optionally, for transmitting data to be stored in the container data storage device using the same method.
  • the data is transmitted from the container data storage device to the processor of the injector.
  • this data already contains specifications in respect of the maximum individual dose and the maximum usage period after opening the container or the processor gathers these specifications from the injector data storage device on the basis of the transmitted specifications in respect of the product identity.
  • the processor of the injector controls the control unit for the pump or the motor such that no more than the maximum individual dose is applied at one time, i.e. without interruption or within a specific period of time, and/or that there is no application from a container or the large cartridge beyond the maximum usage period.
  • a signal for the processor is triggered either manually by the user or automatically. Automatic triggering of such a signal can be brought about by coupling a multi-dose container or the large cartridge to the injector or by coupling a multi-dose container or the large cartridge to a connection to the injector.
  • the processor checks whether the utilized multi-dose container or the large cartridge has passed the expiry date.
  • the expiry date is either gathered from the injector data storage device or it is transmitted to the processor from the container data storage device.
  • the injector can furthermore have a screen, which is likewise connected to the processor.
  • the product information from the injector data storage device or the transmitted product information from the container data storage device can be displayed on the screen. Warning notices when reaching the maximum dose, the maximum usage period or if the expiry date has passed can also be displayed on the screen and/or become audible by means of an acoustic signal.
  • the apparatus for data transfer of the injector is suitable for interchanging data wirelessly (radio waves, infrared) or via a cable connection (also e.g. optical waveguides) with further data storage devices.
  • these further data storage devices may be associated with a scanner for diagnostic purposes, a database within an apparatus for medically caring for patients or with other systems for logistics, ordering procedures or invoicing services provided.
  • Information in respect of the injection protocol can be transferred to the further data storage devices from the injector.
  • Information in respect of the injection protocol include, inter alia, type of applied solution, applied solution amount, time/time period of the application, dose, flow rate, maximum pressure during the injection of the solution and scan delay.
  • Product specific information includes, inter alia, product name, concentration, filling volume, batch number, and use-by date.
  • the injector can also receive information from the further data storage devices.
  • the information transferred by the injector can be used for further electronic data processing in the following manner:
  • FIG. 1 Pump injector system
  • FIG. 2 Pump injector
  • FIG. 3 Data transfer between pump injector, container data storage device and further systems
